摘要：The invention relates to an encoding method, which uses statistical characteristics of all types of network protocols without requiring specific knowledge of the definitions of individual protocol fields. Network protocols in general contain long contiguous sections, which remain unchanged. Said sections are therefore predicted from the preceding header and do not need to be transmitted. The position of the modified and unmodified fields is also predicted, so that in most cases, transmission of the position co-ordinates is not necessary. Said principle, together with a corresponding differential encoding, achieves a high data compression, as only the modified data and a small amount of overhead need to be transmitted.
